<VV> Catalytic Converter for Corvair

John,

As a solid Sulfur should have no odor, but I have smelled sulfur crystals and there is a faint odor.  If you warm it without burning you get a stronger smell.

I wouldn't call SO2 astringent - I'd call it pungent.  It would be forming an acid in your nose as you smelled it - nasty stuff.
